All versions of OS/2 from 2.0 on were available on CD. 4.0 was simply the first version that wasn't available on floppy at all (though the CD still included floppy images so you could make your own if you were really masochistic)

With that said, if they were to actually port WPS to *nix, that would be cool, especially if its released under a FOSS license. That wouldn't be unprecedented BTW, they actually ported WPS to Windows 3.1 back in the 90s and released it under a FOSS license a few years back: http://www.ibm.com/developerworks/forums/thread.jspa?threadID=18004... AFAIK, nobody's ever done anything with the source code, but it is there in case anybody wanted to port it to a more modern system like WinNT/Reactos or *nix.
